Hi;

for i=1:10
    R"i"= nonzeros(D(i,:)); 
end

I want to create arrays under the for loop. The arrays wont have the same size. For each increment, the name of the array should be R + the increment number (R1, R2, R3 ....).

The desired result is 10 vectors R1 to R10.

Any hints to do it ?

Thank you in advance

Use indexing. Indexing is a MATLAB superpower. If you do not use indexing, then using MATLAB will be very ... difficult.

在 MATLAB Online 中打开

R = cell(10,1) ; 
for i=1:10
    R{i}= nonzeros(D(i,:)); 
end

You can access by R{1},R{2},...R{10}. R is a cell array. You need not to name it as R1, R2...R10.

The aim is to use this arrays with distributionFitter. I build a cell array, but it couldn't be used with distributionFitter. That's why I am looking for another solution.
